Unfortunately it's not straightforward.
Include directives are read and processed as the config file is parsed
(readconf.c, look for "case oInclude"). Percent-token expansion
happens after the config is fully parsed, immediately before it's used
(ssh.c, look for the percent_dollar_expand calls). It would probably
be possible to perform some kind of expansion when Include is parsed,
but it would have different semantics compared to all of the other
expansions, eg
UserKnownHostsFile %r/bar
User foo
does expand UserKnownHostsFile, to foo/bar but
Include %r/bar
User foo
would not.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
